Rising snowline in the Alps

(This video has no audio.)
It is estimated that, as global warming proceeds, regions currently receiving snowfall will increasingly receive precipitation in the form of rain. For every 1ºC increase in temperature, the snowline rises by about 150 metres. As a result, less snow will accumulate at low elevations. As a consequence, nearly half of all ski resorts in Switzerland, and even more in Germany, Austria and the Pyrenees, will face difficulties in attracting tourists and winter sport enthusiasts in the future.
